Sequence PLC Programming for Marking with Laser Engraving Machine :

Step 1 :
a. If Push Button Start = ON Then Emergency Stop To Laser Engraving Machine = ON (Hold ON).
b. If Emergency Stop To Laser Engraving Machine = ON And Ready = ON And Error = OFF And LS Up Vacuum Cups = ON And LS Reverse Vacuum Cups = ON Then Counter Reset To Laser Engraving Machine = Pulse ON ( With Timer ) And Counter PLC = 0 And Marking Start To Laser Engraving Machine = ON.
c. If Marking = ON Then Marking Start = OFF.
d. If Marking Complete = ON Then Next to Step 2.

Step 2 :
a. If Marking Complete From Laser Engraving Machine = ON Then Solenoid Forward for Vacuum Cups = ON.
b. If LS Forward for Vacuum Cups = ON Then Solenoid Down for Vacuum Cups = ON.
c. If LS Down for Vacuum Cups = ON Then Solenoid to Pneumatic Vacuum Generator = ON And Timer Vacuum Activated .
d. If Timer Vacuum Cups = ON Then Solenoid Up for Vacuum Cups = ON .
e. If LS Up for Vacuum Cups = ON Then Solenoid Reverse for Vacuum Cups = ON .
f. If LS Reverse for Vacuum Cups = ON Then Solenoid to Pneumatic Vacuum Generator = OFF And Count-Up To Laser Engraving Machine = ON And Counter PLC Increased by one.
g. If Counter PLC = OFF ( Current Value <> 5 ( Be Changed )) And Emergency Stop To Laser Engraving Machine = ON And Ready = ON And Error = OFF Then Marking Start To Laser Engraving Machine = ON.
h. If Marking From Laser Engraving Machine = ON Then Marking Start = OFF And Goto Step 2.a.
i. If Counter PLC = ON ( Current Value = 5 ( Be Changed ) for 5 Product ) Then Process Marking Stop.
